An Adventure in Space and Time: new pictures of David Bradley, Jessica Raine and Brian Cox

Sherlock co-creator Mark Gatiss has written the 90-minute drama about the early days of Doctor Who

Doctor Who's 50th anniversary is fast approaching and amongst the commemorative treats in store for fans is Mark Gatiss' biographical drama, An Adventure in Space and Time.

The 90-minute film stars David Bradley as first Doctor William Harntnell and will tell the story of the Time Lord's creation back in the 1960s. Penned by the Sherlock co-creator, it also stars Brian Cox, Jessica Raine, Sacha Dhawan, Jemma Power, Jamie Glover and Claudia Grant, and will premiere at a special preview screening on 12 November before coming to BBC2 later this year.

That may still seem a little way off but while you wait, take a look at the set of new pictures released by the BBC...
